Dhrystone is a synthetic computing benchmark program developed in 1984 by Reinhold P. Weicker intended to be representative of system ( integer ) programming.

The Dhrystone grew to become representative of general processor ( CPU ) performance.

The name " Dhrystone " is a pun on a different benchmark algorithm called Whetstone.

With Dhrystone, Weicker gathered meta-data from a broad range of software, including programs written in FORTRAN, PL / 1, SAL, ALGOL 68, and Pascal.

From this he wrote the Dhrystone benchmark to correspond to a representative mix.

Dhrystone was published in Ada, with the C version for Unix developed by Rick Richardson (" version 1. 1 ") greatly contributing to its popularity.

The Dhrystone benchmark contains no floating point operations, thus the name is a pun on the then-popular Whetstone benchmark for floating point operations.

Both Whetstone and Dhrystone are synthetic benchmarks, meaning that they are simple programs that are carefully designed to statistically mimic the processor usage of some common set of programs.

Other than issues related to compiler optimization, various other issues have been cited with the Dhrystone.

Dhrystone remains remarkably resilient as a simple benchmark, but its continuing value in establishing true performance is questionable.

Dhrystone remains in use 20 years after it was designed by Weicker, a longer life than most software.

CoreMark is a small benchmark released by the non-profit Embedded Microprocessor Benchmark Consortium ( EEMBC ) that targets the CPU core, similar to Dhrystone.

Dhrystone tries to represent the result more meaningfully than MIPS ( million instructions per second ) because instruction count comparisons between different instruction sets ( e. g. RISC vs. CISC ) can confound simple comparisons.

Thus, the Dhrystone score counts only the number of program iteration completions per second, allowing individual machines to perform this calculation in a machine-specific way.

However, the strings in Dhrystone are of known constant length and their starts are aligned on natural boundaries, two characteristics usually absent from real programs.

Another common representation of the Dhrystone benchmark is the DMIPS ( Dhrystone MIPS ) obtained when the Dhrystone score is divided by 1757 ( the number of Dhrystones per second obtained on the VAX 11 / 780, nominally a 1 MIPS machine ).

Then, on July 2, there occurred another incident which set tongues to wagging at a furious clip.

On Fridays, the day when many Persians relax with poetry, talk, and a samovar, people do not, it is true, stream into Chehel Sotun -- a pavilion and garden built by Shah Abbas 2, in the seventeenth century -- but they do retire into hundreds of pavilions throughout the city and up the river valley, which are smaller, more humble copies of the former.

It was to provide a safe and spacious crossing for these caravans, and also to make a pleasance for the city, that Shah Abbas 2, in about 1657 built, of sun-baked brick, tile, and stone, the present bridge.

In his Message of December 2, 1862, he put his purpose and his policy in these words -- which I would call the Lincoln Law of Liberty-and-Union: `` In giving freedom to the slave, we assure freedom to the free ''.

We assume for this illustration that the size of the land plots is so great that the distance between dwellings is greater than the voice can carry and that most of the communication is between nearest neighbors only, as shown in Figure 2.

In Figure 2, the points in the network are designated by a letter accompanied by a number.

In any social system in which communications have an importance comparable with that of production and other human factors, a point like f in Figure 2 would ( other things being equal ) be the dwelling place for the community leader, while e and h would house the next most important citizens.

This is important to understanding the position that doctrinaire liberals found themselves in after World War 2, and our great democratic victory that brought no peace.

Helen Deutsch informed us ( The Psychology Of Women, Vol. 2,, 434 ) that in all cultures `` the term ' stepmother ' automatically evokes deprecatory implications '', a conclusion accepted by many.

While convalescing in his Virginia home he wrote a book recording his prison experiences and escape, entitled: They Shall Not Have Me Published originally in ( Helion's ) English by Dutton & Co. of New York, in 1943, the book was received by the press as a work of astonishing literary power and one of the most realistic accounts of World War 2, from the French side.

On the morning of September 2 the Fourth Corps and the Armies of the Tennessee and the Ohio followed the line of Hardee's retreat.

In the midst of this gloom, at 10:05 P.M. on September 2, Slocum's telegram to Stanton, `` General Sherman has taken Atlanta '', shattered the talk of a negotiated peace and boosted Lincoln into the White House.

From the night of August 30 to the morning of September 2 there was no Union cavalry east of the Macon railway to disclose to Sherman that he was missing the greatest opportunity of his career.

The attack started on October 2, 1643, and the Gortonists held out for a day and a night.

The wholesome activities were to be provided by many organizations including the YMCA, the Knights of Columbus, the Jewish Welfare Board, the American Library Association, and the Playground and Recreation Association -- private societies which voluntarily performed the job that was taken over almost entirely by the Special Services Division of the Army itself in World War 2.

The third Act of Faust 2, is a formal celebration of the union between the Germanic and the classic, between the spirit of Euripides and that of romantic drama.

Blackman was to be in New York by February 2, because they were sailing at 12:01 next morning.

The fourteenth name was ( Richard ) Buckenham, written Buckman, admitted to Christ's College under Scott 2 July 1625.

Citing the experience of the Combined Chiefs of Staff in World War 2,, Eden said that all would have been confusion and disarray without them.

At the end of World War 2,, free Europe was ready for a new beginning.

What is required is the full implementation of Article 2 of the Treaty, which provides: `` The Parties will contribute toward the further development of peaceful and friendly international relations by strengthening their free institutions, by bringing about a better understanding of the principles upon which these institutions are founded, and by promoting conditions of stability and well-being.

The editorial was based on a news association dispatch which said that the telegraphers had secured an agreement whereby they were guaranteed 40 hours' pay per week whether they worked or not and that a reduction in their number was limited to 2 per cent per year.
